Extraction of Dicarboxylic Acids by ABC Extractants

Solvent Extraction and Ion Exchange, 2004
Abstract Extraction of various dicarboxylic acids (maleic, malic, malonic, succinic, and tartaric) by acid–base couple (ABC) extractants was studied. The main extraction mechanisms were found to be ion‐pair and hydrogen‐bond formation. The relative contribution of each mechanism and extraction efficiency were found to be controlled by parameters such ...

Extraction of carboxylic acids with neutral extractants

Theoretical Foundations of Chemical Engineering, 2017
In the review, the features of the interphase distribution of weak acids (K а < 10–2) in the systems containing neutral extractants have been considered. Experimental results of studies of the extraction of monocarboxylic acids have been described.

Extraction of acetic acid by binary extractants

Russian Journal of Inorganic Chemistry, 2013
Interface distribution of acetic acid has been studied in systems with binary extractants, namely, trioctylmethylammonium di(2-ethylhexyl)phosphate, di(2-ethylhexyl)dithiophosphate, and dinonylnaphthalenesulfonate. It has been determined that, with the increase in the strength of the organic acid involved in a binary extractant, the extraction ability ...

Carboxylic acids as metal extractants

Talanta, 1974
One of the problems in the extraction of trace elements is that matrix elements must usually be masked, involving the addition of large amounts of extra reagent and thus increasing the risk of contamination. If the maxtrix element is to be removed, an extraction system of high capacity is needed to avoid dilution effects. In this respect, long-chain or

Extraction of Amino Acid with Organophosphorus Extractant

1992
ABSTRACT Extraction of amino acids and their related compounds with di(2-ethylhexyl)-phosphoric acid(D2EHPA) dissolved in benzene was studied. Distribution ratio of amino acid D was proportional to the fraction of amino acid in the form of zwitterion.
